Mercury
There are alot of planets in the Milky Way Galaxy. One of them is Mercury, which has approximately 0.39 AU distance from the un making it the closest planet from there. Although, it is also the smallest, it has a diamter of 4,878 kilometers and its mass is about 5.5% of Earth's. Mercury is quite an interesting planet because it's temeratures are so extreme. For example at one point it could be 987 degrees, and the next it could be -287 degrees. That is why no one has been able to step foot or explore on this planet. Mercury is terrestrial as well as all of the other inner planets. It also has no moons. The time it takes for Mercury to make a whole revolution around the Sun is 88 days, and the time it takes for it to rotate on its axis is 58.7 days. It's surface is rocky with craters formed by meteorites and is covered with traces of hydrogen and helium in its atmosphere.

Saturn
Saturn is categorized in the outer planets group of the Milky Way Galaxy which makes it a gas giant. It's average distance from the Sun is 9.58 AU making it the sixth planet from the Sun. This planets diameter is 120,536 km and is the second largest planet in the solar system. Saturn has 62 moons. The time it takes Saturn to make one rotation on its axis is about 10.7 hours, and the time it takes to make a whole revolution around the Sun is 29.7 years. Its core is made up of rock and iron surrounded by ice and liquid hydrogen, it is very cold, and also has strong winds with swirling clouds of ammonia in atmosphere. The current weather for Saturn is at -130'C (-202'F).

These beautiful rings are made up of dust and bits of ice
and rock that refract the Sun's rays to produce all those pretty colors.
Our Moon
The moon is an average of 380,000 km from Earth. It has 7 different fases including: Waxing Crescent, First Quater, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent. How it came to be is undefined, though it is thought to be formed from the debris when a planet-sized object collided with Earth billions of years ago. The moon also does not produce light of its own, it reflects the light from the Sun shining on it at an angle.

Stars
A star is a huge, hot, glowing ball of gas that shines because of processes that go in them that produce huge amounts of energy. Stars live for billions of years that start out as clouds of gases and dust called stellar nurseries. The different types of stars are dwarf stars, neutron stars, blue-white stars, and super giants. Most stars can even be much, much bigger than our very own Sun.
